SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 608,601, dated August 9, 1898.

Application filed February 25, 1898. Serial No. 671,638. (No model.)

To all whom it may concern.-

Beitknown that we, GUSTAV HENNEBERG, I

a citizen of Germany, and FREDERICK BERG- MANN, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and. useful Improvements in Sash-Fasteners, of which the following is a specification.

This invention relates to improvements in sash-fasteners, and more particularly to that class of sash-fasteners in which a locking device upon the sashframe is arranged to engage with the window-frame and hold the sash in an elevated or open position, thus obviating the necessity for the use of sash-cords, with their attached weights, and of sash-boxes, in which such weights are usually suspended.

The object of the invention is to provide a sash-fastener of the class described which shall be simple in construction and operation, of neat appearance when applied to the window-frame and sash, and which shall permit the raising of the sash into any position, the fastener then holding the sash in the position to which it has been raised; and the object is, further, to provide means whereby the sash may be locked securely in its lowermost position against lifting from the outside, so as to afford protection against intruders, and, further, to so construct the sash that the weakest parts and those most subject to breakage may be removed without removing the window from the casing and without removing the entire fastener from the sash and window-frame.

The invention consists of a saslrfastener comprising a slotted guide-plate attached to the sash, bolts located in a bore formed in the bottom rail of the sash and adapted to project therefrom at opposite sides thereof, transverse handle-pieees attached to the inner ends of the bolts and extended through said guide-plate, a dividing-partition in said bore between the inner ends of said bolts, springs located between said partition and the handlepieces for actuating the same, and racks arranged on the jambs in the window-casing, and, further, in certain details of construction and combinations of parts to be more fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a perspective View of a window sash, showing our improved saslrfastener attached to the sash. Fig. 2 is a horizontal section of the same, and Fig. 3 shows in detail the lower portion of one of the racks.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a window-frame of the usual construction, with the exception that the sash-weight boxes at either of its sides are omitted,likcwise the sash weights and cords.

13 represents the lower, and B the upper, window-sasln Each of the window-sashes B B is provided in its side rails with a longitudinal recess 0, extending from the top to the bottom of said rails. A bore 0 of suitable diameter is formed in the lower rail of each sash, and a slot a of suitable size is cut out at the center of the lower rail through to the bore. A guideplate D, provided with a slot cl of approximately the same size as the slot at, is attached centrally to said lower rail, said slot cl registering with the slot or in the sash. Bolts E of suitable length and having, preferably, beveled outer ends are guided in the bores O and provided at their inner ends with handle-pieces F, projecting through the slot a and plate D, so as to afford means by which the bolts E may be moved longitudinally in the bores C, andas well a convenient handle for raising or lowering the window. To prevent excessive play and secure more reliable action of the bolts E, guide-blocks Z2 are inserted in the bores 0, near the outer ends of the same, by which the bolts are sup ported. Racks G, having teeth 9 g and openings g at the lower ends of said racks, are attached to the jambs of the window-frame, so as to enter the recesses in the side rails of the sash. Springs H H are placed between the inner ends or handle portions F of the bolts E and a dividing-partition h, secured by being driven into the adjacent Wood of the sash-frame between the inner ends of the bolts, as shown in Fig. 1. By the springs the bolts E are forced apart-and their outer ends kept in engagement with the teeth of the racks G, or, if the sash happens to be lowered, instead of engaging with the teeth g the projecting bolt ends enter the openings g, thereby securely locking the sash in its lowermost position, so as to prevent it from being opened from the outside.

When it is desired to raise the sash from its lowered position, the handle-pieces F are taken hold of and pressed together with the fingers, thus withdrawing the ends of the bolts E from engagement with the openings g and compressing the springs H H. The sash may now be freely raised to the desired elevation with one hand by means of the handle-pieces without releasing them. l/Vhen the desired elevation is attained, the hold of the fingers upon the handle-piece is released and the springs H H return the bolts to their original position, thereby forcing them into the teeth g g of the racks and retaining the sash at the elevation to which it has been raised.

It will be seen that after having been released from its locked position at the bottom of the sash in the operation of opening the window it is not necessary to use care that the handle-pieces F be kept pressed together, as if they be allowed to separate while the window is being raised the effect will be that the projecting ends of the bolts E will be forced by the springs H H against the rackteeth g, and 011 account of the beveled ends of the bolts and the upward trend of the teeth the bolt ends will slide readily upon the teeth and little or no resistance will be offered to the upward movement of the sash.

To lower the window, it is necessary to grasp the handle-pieces F and press them together in the same manner as when raising the sash, only that care has to be taken to keep the handle pieces pressed firmly together, so that the bolt ends may not project and engage with the rack-teeth and thus stop the downward movement of the sash. The sash having been lowered as far as may be desired, the grasp of the fingers upon the handle-pieces F is released, and the bolts are immediately forced apart by the action of the springs, causing them to engage the adjacent teeth of the rack, thereby holding the sash firmly in position, as before. If the grasp be not released until the sash reaches the bottom of the window, the projecting bolt ends, instead of engaging with teeth, enter the openings 9, as shown in dotted lines in Fig. 1, thereby locking the sash at its closed position.

When it is desired to lower the upper sash, the lower sash is first raised until the handlepieces in the lower rail of the upper sash are exposed, and the upper sash can then be adjusted in the same manner as the lower sash, as before described.

The springs H H, as shown in the drawings, are located in the bore back of the central guide-plate D and compressed between the dividing-partition and the handle-pieces of the bolts. By this arrangement,as the springs become weak or break or as the handle-pieces break or work loose, to repair the parts or replace the same with new parts it is only necessary to remove the central guide-plate, when the springs, the inner ends of the bolts, and the handle-pieces are exposed and the necessary repairs may be made. By means of the dividing-partition each side of the device is made independent of the other side and only the defective portions need be disturbed. The removal of the plate does not dislocate the parts in any manner, but gives access to them without removing the sash from the window-frame.

While the device maybe used upon the windows of all structures, it is particularly valuable when applied to the windows of railway-cars or other vehicles where no sashweights can without great inconvenience and expense be employed.

Having thus described our invention, we claim as new and desire to secure by Letters 1atent A sash fastener, consisting of a slotted guide-plate attached to the sash, bolts located in a bore formed in the bottom rail of the sash and adapted to project therefrom at opposite sides thereof, transverse handle-pieces attached to the inner ends of the bolts and extended through said slotted guide-plate, a dividing-partition in said bore between the inner ends of said bolts, springs located between said partition and the handle-pieces for actuating the bolts, and racks arranged on the jambs of the window-casing, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
